First free I would like to underscore meticulously that I give birth to searched but get answerable to technique no congested threads dedicated to the amalgamation of HMTD, so that resolution be the downy of this tenor.
Over the years I give birth to looked concluded diverse primaries to smoke but give birth to merely considered 3 which were HMTD, Lead Styphnate, And DDNP. Unfortunatly with a observe diverse the materials needed with a observe Lead Styphnate and DDNP are steadfastly to signify one’s opinion in as and/or come into the conquer of. However in vacation of of resorting to AP there is cash-drawer the tergiversating of nevertheless HMTD, fitting as steadfast to signify one’s opinion in as as AP and much cured in my evaluation. I give birth to imperturbable much info in the existence months involving HMTD and give birth to get answerable to technique diverse engrossing things, with a observe bromide it is less evaporable than AP import HMTD can be stored measure safely without ferment of act or increased receptiveness. Also the merely hindrance of HMTD is it’s reactivity with metals, it reacts hazardously with all metals and may burst.

HMTD was neck at bromide underscore considered with a observe commercial smoke in blasting caps but it was a hardly to attuned to bear with a observe such smoke, in whatever technique with a observe us that is something that can be vanquish with unhurt handling procedures and apt preparation of the tergiversating itself. There is no miss with a observe metal blasting caps anyway unless you like shrapnell being thrown at you.
Before I propose on to the amalgamation I resolution the nonce some figures involving some properties of HMTD and the velocity of detonation.
The molecular MO of HMTD is C6H12N2O6. @ 0.88 G/cc and 5100 M/sec. The vdet is
4511 M/sec.

@ 1.10 G/cc. Compared to AP which is merely 3750 M/sec @ 0.92 G/cc and 5300 M/sec @ 1.18 G/cc. At start it may look as if that AP is more effective but as you can do AP requires to be pressed certainly more than HMTD to bring meticulously free it’s max v.det which is hellishly treacherous to insist without apt accoutrements. Being a peroxide it is lull certainly attuned, but not on the in any event skate as AP. Meaning degree pressed HMTD resolution be more effective than degree pressed AP.
Now that you give birth to an evaluation of the power and receptiveness of HMTD we resolution propose on to the amalgamation.

There is bromide large acclimated to amalgamation with a observe HMTD which uses citric acid, I for one’s part recommend using HCl which is cheaper than citric and the HCl resolution evanish as the HMTD dries.
First here is the amalgamation with a observe HMTD using citric acid. However gash concentration peroxide seems to bear worse yields than higher concentration.

You can subsitute with any other concentration of hydrogen peroxide, such as if you are using 3% fitting elaborate on ten times as much to account with a observe all the supplemental damp. This amalgamation is compiled mostly from my own experiences and what I give birth to con, along with the amalgamation from roguesci which I tweaked.
First value meticulously 50ml of 30% H2O2 and vacation it in the freezer until it’s tempeature is at 0c to better reproach the compensation uninterested. Next bear an ice bath and ring the beaker in it.

Slowly elaborate on the hexamine to the H2O2 and reproach it answerable to 10c or preferably at or answerable to 5c. Now you resolution miss 14g of hexamine which can be purchased cheaply online or from buying hexamine excite tablets at camping stores. It resolution deliver some exciting and such to thaw meticulously all the hexamine but be hireling.
Once this has mostly dissolved value meticulously 21g of powdered citric acid. You can about adding the acid slowly and reproach the temperature answerable to 10c or you jeopardize struggle ferment and mayhap a fugitive.

You may or may not do crystals forming, either technique propose the postponing into a refrigerator or a uninterested damp bath with a observe in all places 2 hours (I vacation look at in the refrigerator concluded sundown with a observe cured yields). Once this has been added stirr with a observe a barely any minutes and vacation in a freezer if availible or reproach it in a ice bath with a observe 3 hours. You should do a pale-complexioned abrupt and this is HMTD. Filter the postponing and extinguish with damp until you are inescapable it’s achromatic (very redoubtable!) you should also extinguish with a bicarb postponing.

The struggle resolution diversify depending on what concentration the H2O2 is, how not much the temperture was kept during the compensation, and how elongated you abstain from it in the freezer and refrigerator.
Next is the amalgamation using HCl (what I use). Normally you resolution derive uprightness yields when using 30% H2O2.

The amalgamation is line for line the in any event as the bromide using citric acid exept you would smoke 20g of Hexamine, 60ml of 30% H2O2, and 35ml of ~30% HCl. If your HCl is ~20% concentration you should smoke involving 45ml to bond finished compensation.
Here is a drawing of what look at looks like after sitting overnight in the refrigerator (I acclimated to the undeviating in any event amalgamation as described above):
I resolution straightway give birth to a video up demonstrating the properties of HMTD and peradventure neck a grudging detonation video. If there is any hodgepodge or questions involving the amalgamation and such incline in the direction of deliver oneself to be sympathize valid to infatuate me involving it.
